This method creates an elliptically curved path between points.
Syntax
Parameters left X coordinate of the topleft corner of the bounding rectangle
top Y coordinate of the topleft corner of the bounding rectangle
right X coordinate of the bottomright corner of the bounding rectangle
bottom Y coordinate of the bottomright corner of the bounding rectangle
firstX X coordinate of the 1st point
firstY Y coordinate of the 1st point
secondX X coordinate of the 2nd point
secondY Y coordinate of the 2nd point
Return valueIf successful, this method returns S_OK. If it fails, this method should return one of the error values.
RemarksThis method draws a path as a part of an ellipse that is bounded by the rectangle with topleft corner (left, top) and bottomright corner (right, bottom). The arc is drawn following the perimeter of the ellipse, counterclockwise, from the starting point to the ending point. The starting point is defined by the intersection of the ellipse and a line drawn from the center of the ellipse to the point (firstX, firstY). The ending point is defined by the intersection of the ellipse and a line drawn from the center of the ellipse to the point (secondX, secondY). This method also draws a line from the current position to the starting point.
